  • This study aims at establishing a sizing system required for producing ready-made clothes which can fit the body shape of disabled men using wheelchair. It measured the bodies of 178 adult men using wheelchair and compared the sizing system of German adult men using wheelchair (1984) with KS system(KS K0050, 2004) in order to establish standards of the sizing system. AS a result, in terms of classification of body shapes, KS system cover more types of disabled men's body shapes and especially, A types (Drop 15.6) showed the widest coverage with 32%. In classification of heights, the widest range of height was 170 cm, and Korean men's four sizes between 158 cm and 176 cm covers 88.2% of disabled men's body shape. For chest size, 91.1% of disabled men's chest sizes were included in seven sizes, which are 4 cm intervals between 88 cm and 112 cm with 100 cm standard. In consideration of the ranges of height and chest, the general sizes (A types; 11 sizes, B types; 3 sizes, Y types; 5 sizes) are selected to present the standardized measurements. Basic parts of the upper garment sizing system for disabled men using wheelchair were height-chest-waist size.

  • Apparel companies define their target customers to integrate consumers' needs into their product development processes. The sizing standards play a significant role in ready-to-wear garment business. Consumers' body build and sizes are different according to gender, age, and body type. The consumers' morphological feature of the one geographical area has changed with immigration, aging, and lifestyle change. In this study the way of defining body types in the standard garment sizing systems published in USA., UK, Germany, Japan, and Korea were compared. The results of this study show that most of the systems classified the body types by the index value. The chest-waist drop value was used for men's body type classification. Women's body types were defined by hip proportion. The hip-bust drop value was used for it. German and European garment sizing systems provide a wide range of men's body types. US men's garment sizes are developed for very conservative body type. US women's garment sizing system has had clearly defined women's body types. The Misses body types projected in the US garment sizing system had changed as women's waist girth got bigger compared to the past. In 2011 the US Misses sizes were divided into Curvy Misses size and Straight Misses size by the hip-waist drop value. The Curvy Misses sizes have smaller waist girth and larger hip girth than the Straight Misses sizes.

  • Polyethylene terephtahalate has been used in several areas such as fiber, film, bottle, and disposable products. Production of PET has been rapidly increasing these days. Since PET is a semi-permanent material, it has a non-biodegradable character in itself. Wasted PET products can cause serious environmental problems. Many countries around the world impose environmental legal restrictions over their abandonments. Many researches on the enviromental influence factors and treatment techniques of the wasted PET have been carried out. The main objective of this study is to develop a new sizing agent using recycling PET and improve its internal sizing effect. Dried powder of PET was used to make the modified PET. After extracting water-dispersible PET by subcritical hydrolysis, polyester resins have been extracted and triphenyl phosphate(TPP) has been added to obtain optimal internal sizing agent. It was found that the optimum dosage of TPP was 2% (per PET weight) and the hydrolysis temperature was independent on making the modified PET.

  • It is essential to use base papers having proper surface characteristics in coating operation for improving coated paper quality and coater runnability. To fulfill these purposes, surface sizing of coating base stock with oxidized starch is commonly practiced. Use of cationic starch for surface sizing improves coated paper quality since cationic starch penetrates less into paper structure. The immediate objective of this study was to examine the influence of surface sizing with starch solutions containing cationic polymers on the rheology of coating colors and the effect on physical properties of coated papers. Changes of rheological characteristics of coating colors placed on the plastic substrate surface sized with cationic and anionic starch were determined. Results of rheological test showed that cationic polymer surface sizing agent increased electrostatic interaction with coating colors and increased storage modulus. This new technology of using cationic polymer as surface sizing additive was considered to be advantageous for base papers at low basis weights since it would improve the coverage and optical properties of coated papers.

  • The objective of this study was to develop a school uniform sizing system with high coverage rate for middle school boys, who are in the stage of rapid growth, by identifying problems in existing school uniform sizing systems through surveys of students and uniform manufacturing companies, and analyzing juveniles' physical sizes. For this purpose. the study conducted a survey about how middle school boys choose their uniform sizes, and what complaints they have on the size of the uniforms. In addition, it was investigated what is the current state of uniform manufacturing and sizing systems through a survey of uniform companies, and the study identified problems in the size of school uniforms by comparing physical sizes of juveniles' aged 14 to 16 with the sizing systems of the companies and KS standards in 1997. Juveniles' physical data was a part of the material of the national anthropometric data in 1997. Using the two-way distribution of juveniles' height-bust girth and height-waist girth, this study established the sizing system by increasing the number of sizes for the short interval where juveniles' physical sizes are densely distributed whereas limiting the number of sizes for the long interval where juveniles' physical sizes are rarely distributed, considering the difference between companies' standard and KS' standard.

  • This is a tentative study to provide prototype of sizing system for children's shoes. For this study, 364 elementary school girls from KyungIn and YeongNam areas were participated in the measurement. The results of the analysis on four measurement items related to foot can be summarized as followings: 1. All of the foot related items were increased according to their growth. Especially, foot length, foot width, and toe width showed a high correlation. 2. The result also revealed that the current sizing system can cover only 70.9% of children in measurement, which means that a new sizing system is required. 3. We suggested a new standard size for foot size/foot circumference based on the results above according to current sizing system, and a new standard size for foot circumference/foot width based on ISO standard. The results of this study would be helpful in the design of sizing system of children's shoe if applied with the raw data of the Size Korea recently measured.

  • Generally, a vertical rolling process is used to achieve extensive width reduction in hot strip mill. However, it is impossible to avoid the defects such as dog-bone and edge-seam defect. The sizing press process has been developed in response to the defects mentioned above. Especially, this study is carried out to investigate the deformation of slab by two-step sizing press. The deformation behavior of slab in the sizing press process is more favorable than that in conventional vertical rolling edger. The FE-simulation is applied to predict the deformation behavior of the slab. In this paper, the several causes of the asymmetrical deformation are mentioned for the purpose of understanding of the anvil shape. Load, dog-bone and edge-seam defect are discussed in width sizing process considering the anvil shape. And to reduce the problems generated at rougher mill just after sizing press, these are studied in this paper. The deformation behavior of slabs and optimum anvil shape are obtained by rigid-plastic finite element analyses and neural network.

  • The periodic inspection of piping and pressure vessels welds in nuclear power plant has to provide reliable result related to weld flaws, such as location, maximum amplitude response, ultrasonic length, height and finally the nature or flaw pattern. The founded flaw in ultrasonic inspection is accepted or rejected based on these data. Specially, the amplitude of flaw response is used as basic parameter for flaw sizing and it may cause some deviation in length sizing result. Currently the ultrasonic inspections in nuclear power plant components are performed by specific inspection procedure which describing inspection technique include inspection system, calibration methodology and flaw characterizing. To perform ultrasonic inspection during in-service inspection, reference gain should be established before starting ultrasonic inspection by the requirement of ASME code. This reference gain used as basic criteria to evaluate flaw sizing. Sometimes, a little difference in establishing reference gain between calibration and field condition can lead to deviation in flaw sizing. Due to this difference, the inspection result may cause flaw sizing error. Therefore, the objective of this study is to compare and evaluate the ultrasonic amplitude difference between air filled and water filled pipe in nuclear power plant. Additionally, the accuracy of flaw sizing is estimated by comparing both conditions.
